When selecting the door lock that will best suit the needs of your application, the first and most important thing to consider is the security that the lock will provide. All locks on the market are divided into three categories determined by the standards set by ANSI (American National Standards Institute). Each lock is graded according to security and operational tests created to determine their appropriateness for certain applications.

ANSI has set three categories of locksets, Grades 1, 2 and 3, where Grade 1 is the highest quality. Before looking into any other factors about your door locks, you will need to determine which category set your lock needs to belong to. Here are some important bits of information to help you make that decision:

Grade 1:

In order for a standard door lock to meet grade 1 standards it needs to withstand 800,000 door cycles, six door strikes as well as a 360 pound weight test. For a deadbolt to be graded for this level, it will need to withstand 250,000 cycles and 10 door strikes with a hammer. Since these locks fall into the category of having the greatest safety and durability standards, they are recommended for use in commercial applications and will definitely offer the greatest security for your business or other application.

Grade 2:

Locks that meet grade 2 standards are subject to a test of 400,00 door cycles. 4 strikes to the door and a 250 pound weight test. Deadbolts will need to pass a test for 150,000 cycles and 5 strikes to the door with a hammer. Grade 2 locks are usually not secure enough for most business, however they meet or exceed the needs and requirements for most apartment buildings and other residential applications.

Grade 3:

While grade 3 locks are lowest level according to ANSI standards, they still need to be of substantial quality to meet even these requirements. They are therefore generally recommended for secondary entrances in residential applications. These door locks need to pass a test of 200,000 cycles, 2 door strikes as well as a weight test of 150 pounds. Deadbolts are subject to a test of 100,000 door cycles and 2 hammer strikes to the door.
